This study carried out on a nearly threatened East Coast Akalat (Sheppardia gunningi sokokensis Van Someren 1921) in two forest types (Cynometra woodland and mixed forest) in Arabuko-Sokoke Forest to determine the proximate factors that influenced its spatial distribution. Playback was used to stimulate the bird to reveal its presence. Fifteen habitat factors predicted to be important as cues for habitat selection were recorded from territory and non-territory sites and compared. Normal and logistic regression models were used to select the best habit predictors of Akalat distribution and density. The best habitat predictors for the occurrence of Akalat (in both habits combined) were mossy logs and vegetation cover at 2m; sites without Akalat had higher numbers of cut stems. The greatest amount of food was associated with the presence of Akalat; large territories were located in the mixed forest compared to the Cynometra woodland; the bird was more evenly distributed in the Cynometra than in the mixed forest; higher population density was recorded in the Cynometra than in the mixed forest. Results suggest that; East Coast has the ability to select micro habitats suitable for its survival; human activities affect the population density and distribution of Akalat by affecting vegetation structure suitable for the Akalat; mossy logs and vegetation cover at 2m high can be used as quick rapid indices in predicting habitat quality for the Akalat.Page Range
